Hi Mike
It really comes down to trial and error fitting. It depends on the size and location of the nipples on the engine and rad. I then looked up a couple of hose company catalogs and went through them until I found some that looked close. Then I went to NAPA and ordered probably 8 or 9 different hoses for trial fitting. Finally found 2 that would work on my 6.1 setup with some trimming.
I ended up with NAPA 9128 upper and NAPA 7515 lower, but they may or not work for your setup.
